To kill fleas and prevent reinfestations, apply to cats and kittens 8 weeks of age and older as follows: 1. Use only on cats and kittens 8 weeks of age and older and weighing 1.8 lbs. or more. Do not use more than a single dose on cats weighing greater than 20 lbs. 2. Remove one applicator tube from the blister package. 3. Hold the applicator tube in an upright position. 4. Press cap down until it clicks.(Indicating the tube has been punctured). Hold upright and remove cap. Check to be sure there is an opening at the tip of the tube. 5. Part the hair on the neck at the base of the head until the skin is visible. Place the tip of the tube directly above the skin and squeeze the tube 2-4 times to expel the contents of the tube directly on the skin. For best results, apply at the base of the head, not between the shoulder blades. Avoid getting the product on your pet's mouth or eyes. Treatment at the base of the head will minimize the opportunity for the cat to lick the product. Do not allow your cat to ingest this product. (There may be a small residual remaining in the tube after a full dose is expelled. 6. discard empty applicator tube in the trash.
